If you can't see behind the furniture or appliances, then it's clean back there.
An unmade bed will still be there tonight, ready for you to crawl into.
There are three things you can do with dirty laundry:
(Traditional) Wash/Dry/Iron/Fold/Put it away.
(Efficient) Wear it! It's probably clean enough!
(Philanthropic) Donate it! You wanted to shop for new clothes anyway!
Remember dust and dirt go under the rug. Trash and debris go under the sofa!
Get rid of your dust rags, vacuum cleaner, mops and brooms, and buy a leaf blower.
